basically you need to translate apaches "ErrorDocument 404 /misc.php?google_seo_error=404" to whatever that is in Windows Server. I don't know Windows Server, sorry. Either way, this is a matter of webserver configuration...

@frostschutz ty i have found the 404

do you have custom pages for other codes such as 403 etc?

[frostschutz]

403 and other codes are issued by MyBB's own error handler, they should show up fine unless your webserver suppresses error codes sent by PHP and displays their own error message instead. Otherwise you can also just send 403 errors to google_seo_error=404 to display the same generic error page for them.
